MACHINE CONTROLS
Front Panel
CAMERA BACKLIGHT JACK
This jack is directly controlled by the Intensity Knob described above.
LCD
The Liquid Crystal Display is used by the 454647E to communicate machine status, menu
prompts, explanations, and options. Four lines of text are available and each line is capable of
displaying 40 characters.
Z
CONTROL LEVER
Located at the far left on the machine front panel, this lever acts to bring the tool down to bond.
As with the manipulator arm, W
EST•BOND includes two Z-control levers (one high position style
and the other low position style).
G
O BUTTON (NOT SHOWN)
This is the small push-button switch located in the manipulator control ball. The Go button
controls two different features depending upon how it is used. When the button is quickly pressed
and released it operates the X-Axis braking system. This is done to aid the operator in scanning
the bond path along the Y-Axis. If this button is pressed and held, the bonder automatically goes
to Search before first bond. It pauses at search until the Go button is released. Once released,
the machine will complete the bonding sequence (if in Full-Auto mode). If the machine is set in
Half-Auto mode, it will pause before each operation, requiring a press of the Go button to
proceed.
Key Pad
The KEY PAD, located on the left-hand side of the machine, enables the operator to access the
programmable and high level functions of the machine. Take extra time to read the LCD during
your first few programs for guidance to proper key strokes. Soon enough an operator will develop
time saving memorization of the menu’s and their location in the software. See the key format in
Programming section for more details (pages 40 to 87).
The following reserved keys will be used in most menus:
K
EY 1 = PREVIOUS MENU or ESCAPE - Press key “1” to escape
to the previous menu.
K
EY 2 = GO TO - Press key “2” for Go To options, such as: Go
To Device, or Go To Type.
K
EY 3 = HOME - Press key “3” to escape from any menu level,
or to return to the Align or “Home” Menu.

MACHINE CONTROLS
Crosshair Generator Controls
P
OWER
Activates the Crosshair Generator. Even if the crosshairs are not used, this unit must be turned
on for the video signal to be passed through to the monitor.
F
ILL
This switch turns the crosshairs on and off on the monitor.
I
NTENSITY
Controls the color and brightness of the crosshairs. When the Intensity knob is turned all the way
counter-clock wise, the crosshairs are bright white. When the knob is turned all the way clock
wise, the crosshairs will be black. Depending upon the package, the user may select between
these two colors to allow greater crosshair visibility.
H
ORIZONTAL CONTROL
This digital potentiometer controls the position of the horizontal crosshair. Increasing this number
lowers the position of this crosshair, while decreasing this number raises the crosshair on the
display screen.
V
ERTICAL CONTROL
This digital potentiometer controls the position of the vertical crosshair. Increasing this number
moves the position of this crosshair to the right, while decreasing this number moves the
crosshair on the display screen to the left.

Negative Electronic Flame Off
POWER SWITCH
The power switch turns the power on to the NEFO unit. Always turn this unit off when servicing the torch
or head assembly.
P
OWER DIAL
Sets the Ball Forming Current to a constant. The voltage will vary to keep the power the same to
consistently make the same size ball each time. The power dial will set the current from 7.5ma – 25ma.
The current setting can be adjusted to a 9ma – 35.5ma range for larger balls on 1.5 – 2.0 mil wire.
Jumper E1 on the mother board (Lower PCB) should be changed from pins 1-2 to 2-3 for the high power
setting.
T
IME DIAL
Ball Forming Time, or a cut-
off time for ball formation.
Forming time is set between
2.1ms to a maximum of
10ms. Factory setting of the
time is at 2.5 (approximately
4ms), this is the optimum
setting.
LED’
S
The Open and Short LED’s
are for designation of a ball
fault. If the Open LED is lit,
then the gap between the
end of the wire and the torch
tip is too large for ball
formation. If the Short LED is
lit, then the wire has
contacted the torch tip
causing a short where no
spark is formed.
